Flue gas waste heat power generation or steam boiler

Direct discharge of 500-degree flue gas? This doesn’t meet national standards! When the amount of flue gas is low, it’s best not to use it for power generation, as the losses are too high. It still depends on the smoke volume and intended use for the design.

““Seeking design for flue gas waste heat boilers or power generation” – what is the goal here? Should I ask the design firm for a quote, or do I want to get a proposal directly? Or would you like to learn about some cases for reference?

Flue gas at 500 degrees is discharged after being directly cooled by circulating water; now we want to make use of this heat energy, and we are seeking a reasonable solution.

Thank you for the reply. I need a proposal and a quote.

There is no best solution – only the most suitable one. It is necessary to understand your current situation in order to find the most appropriate approach. There are two ways to find out: one is to conduct on-site inspections for a comprehensive understanding, and the other is to distribute questionnaires for you to fill out. For a rough estimation, we’d ask several questions, such as the volume and temperature of steam produced by your boilers, or the amount of natural gas consumed, in order to estimate the flue gas flow rate. We’d also inquire about how you utilize the steam. Essentially, it all comes down to cost calculations. If your monthly natural gas expenses amount to only a few tens of thousands of yuan, then there’s probably no point in doing anything, since any savings generated would merely offset those expenses. Only when the expenditures are substantial does it make sense to proceed with such measures

Thank you for answering patiently. I feel like I’m getting a handle on it, thanks.

Our furnace is not a boiler; it is a drying oven used for drying coils. The hot flue gases produced have a high temperature, and at present they are discharged after being cooled. It seems interesting to make use of this thermal energy, so we are looking for options for small-scale power generation or waste heat steam boilers – a complete set of equipment would be ideal.

Currently, it is essential to focus on the integration and utilization of information. Engaging experienced manufacturers can eliminate the need for basic research, development, and design work; this way, potential pitfalls can be avoided, thereby reducing costs. In addition to the economic value of the project itself, it is necessary to understand the local policies and the concept of carbon neutrality, to see if part of the costs associated with equipment investment can be reimbursed. Winning awards or similar recognitions can also bring prestige to the company as well as to the local leaders

Air heat exchange can be used, with hot air being employed for drying, or a hot water boiler can be used to generate hot water
